Abstract
Official abstract text for this publication.
The present invention relates to conjugated polymers. In various embodiments, the present invention provides a conjugated polymer including a repeating unit including a benzene ring conjugated with the polymer backbone, wherein the benzene ring is fused to two 5-membered rings, wherein each fused 5-membered ring includes N and at least one of O and S. In various embodiments, the present invention provides semiconductor devices including the polymer, and methods of making the polymer.
First claim
Opening claim text (preview).
What is claimed is: 1. A conjugated polymer comprising a repeating unit comprising structure (I): wherein each R 1 at each occurrence is independently chosen from —R 2 , —H, —OH, —OR 2 , —NR 2 2 and halide, wherein R 2 at each occurrence is independently chosen from —H and substituted or unsubstituted C 1-60 hydrocarbyl, and each A at each occurrence is independently chos…
